How can I import models from Anim8or into Blender?
Transferring data is just a matter of finding a format that both programs can use. Some formats have better support for some features than others (like materials, animations, and armatures).

It would appear that Anim8or can export in 3DS and OBJ - both can be imported into Blender, menu File -> Import -> 3D Studio (.3ds) or menu File -> Import -> Wavefront (.obj).

Both import addons should be enabled in Blender by default, but if they aren't, open the User Preferences and look under addons to enable them.

I would export in both formats and see which one gives a better result in Blender. I would also expect that the mesh would transfer OK, but then expect to do some manual work to re-make the textures in Blender.
